Calculate the LCM of 840,811,551,348

Given numbers are 840,811,551,348

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 840,811,551,348 is 375363240.

Find LCM of 840,811,551,348 with Prime Factorization


2 840, 811, 551, 348
2 420, 811, 551, 174
3 210, 811, 551, 87
29 70, 811, 551, 29
70, 811, 19, 1

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 29 x 70 x 811 x 19 x 1 = 375363240

Therefore, the lowest common multiple of 840,811,551,348 is 375363240.

LCM Formula to Find Lowest Common Multiple of 840,811,551,348

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

840 x 811 x 551 x 348 = 130626407520

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

811 : 1, 811

551 : 1, 19, 29, 551

348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,811,551,348, is 1.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

811:811

551:19x 29

348:2x 2x 3x 29

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3x 29 = 348

Therefore, the value for common factors is 348.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 130626407520/(1x348)

LCM = 130626407520/348

LCM = 375363240

Thus, we can understand that the LCM of 840,811,551,348 is 375363240.
